  1. Two-level nested ANOVA evaluating differences in dry weight, elemental composition and proximate biochemical composition among months and hatches nested within months; interaction between these factors; biomass parameters: (W) dry weight, (C) contents of carbon, (N) nitrogen, (H) hydrogen, C/N ratio, lipid, protein and (E) energy; significant differences marked with asterisks (* P < 0.05; ** P < 0.01; *** P < 0.001)
